My Dishwater Won’t Drain! – 4 Reasons Why

You really don’t know the convenience of having a dishwasher until it suddenly malfunctions, or completely stops working! Being able to cook a delicious meal for your family and having the luxury of placing your dishes into a machine that cleans them is a no-brainer! Have you had the unfortunate circumstances of your dishwasher not draining, leaving you wondering why?! No need to worry, we’re here to explain 4 common reasons why this may be happening and quick solutions for you to try at home before calling the professionals at Greenwood!  


  1. Dirty Filter 

One of the common reasons why your dishwasher may not be draining is due to a dirty filter. First, you should identify where the filter is located on your machine. Once you have found the filter, make sure you thoroughly wash it and then replace it back to its original spot. After cleaning the filter and putting it back in its place, do a test run to see if there are any improvements.  


  1. Garbage Disposal Blockage  

One of the less obvious causes of your dishwasher malfunctioning is a garbage disposal blockage. There is a hose that connects your dishwasher to your garbage disposal, and when the garbage disposal is blocked with food or grease, it can cause delayed movement of water causing the standing water effect. Sometimes, letting the machine run for a couple of seconds can do the trick, if not- call to schedule your drain cleaning with Greenwood!  


  1. Incorrect Detergent  

According to, a common culprit of a clogged dishwasher is the type of detergent you are using! Surprisingly, most machines are made for powder detergent, and not liquid. While using liquid detergent sporadically can get the job done, the liquid detergent creates many suds, preventing water from properly draining after the cycle. Make sure to check your machine to see which detergent is recommended!  


  1. The Drain Hose is Blocked 

If cleaning your filter and confirming there is no blockage from the garbage disposal doesn’t solve the issue, confirm there is no blockage in your drain hose (which carries dirty water away from the appliance).  While this issue is usually more uncommon, there may be built-up debris or a kink in the pipe causing a blockage.
